Abstract
A system and method facilitate drilling of a lateral wellbore by eliminating one or more trips downhole. The system comprises a drill bit optimized for the drilling operation. The drill bit is coupled to a whipstock via a connector, which minimizes interference with the cutting elements of the drill bit. The connector includes a separation device which facilitates disconnection of the drill bit from the whipstock after the whipstock is anchored at a desired downhole location. The separation device is disposed in the connector to minimize the remaining portions of the connector existing after separation of the drill bit from the whipstock which must be milled by the drill bit prior to drilling the lateral wellbore.
